Pickerel has its own dedicated 10-digit line (0304490106) under HTS Chapter 03, distinguishing it from other freshwater species. Walleye and pike would fall under separate species-specific lines or the NESOI residual line if no dedicated code exists, so correct species identification at entry is essential to avoid misclassification.

Importers must file an FDA Prior Notice for all food shipments, and the foreign processing facility must be registered with FDA. A commercial invoice, packing list, and bill of lading are standard entry documents; some ports may require a catch certificate or country-of-origin documentation depending on the source fishery.
